Method for cleaning cathode tubes of electrolysis coloring troughs of aluminum profiles

Abstract

The invention discloses a method for cleaning cathode tubes of electrolysis coloring troughs of aluminum profiles. The method comprises the steps that a conductive material is mounted on an anode of a coloring trough, a cathode of the coloring trough is connected with a positive electrode of a power supply, and the conductive material is connected with a negative electrode of the power supply. An electrolyte solution of the coloring trough is charged with direct current, and the cathode tube of the coloring trough is subjected to electrochemical reaction under the electrochemical action, so that metal impurities attached to the surface of the cathode tube of the coloring trough are dissolved in the electrolyte solution of the coloring trough. According to the method for cleaning cathode tubes of electrolysis coloring troughs of aluminum profiles, the cathode and the anode of the coloring trough are switched automatically by switching power supplies of the coloring trough, and the conductive material is mounted on the anode, accordingly, metals and other oxides on the cathode tube can be automatically dissolved in the electrolyte solution under the electrochemical reaction, and further, the cathode tube is not needed to be detached, and the purpose of online cleaning can be achieved. The method is simple to use and good in cleaning effect, improves the conductivity of the cathode, and is uniform in the aluminum profile coloring.

Description

technical field [0001] The invention relates to the field of chemical batteries, in particular to a preparation method of a lithium-ion battery carbon negative electrode material with a graphene-like structure. Background technique [0002] After aluminum is anodized in sulfuric acid solution, an oxide film is formed on the surface of the product. The outermost surface of this oxide film is porous. It is called a porous layer, and the bottom layer of the oxide film is in contact with the aluminum substrate, which is a thin layer of dense oxide film, also known as the active layer or barrier layer. The aluminum material with anodized film is immersed in the electrolyte of some metal salt and used as an electrode (because of alternating current), while the other electrode can be made of the same pure metal plate or metal salt contained in the electrolyte. Graphite, stainless steel plate, etc. When the two poles are connected with alternating current at the same time (general...
